About the Channel :
Core Engineering is a UA-cam Channel for those Engineering Students as well as Engineers i.e. Chemical Engineer, Process Engineer, Instrumentation Engineer, Mechanical Engineer, Electrical Engineer, Electronics Engineer, Civil Engineer, etc. who wants to learn about the Engineering concepts from the scratch, wants to know the Technical How of each concept and those engineers who are already working in a Industry.
We will upload the videos related to Industrial concepts i.e. Pump, Centrifugal pump, Reciprocating pump, Compressor, Centrifugal compressor, Heat exchangers, Valves, Reactors, Plant shut down and plant start up, Process safety during plant startup and shutdown and Software used in an Industry, Industrial Engineering, Process Engineering related videos.
That is why! You must Subscribe the Core Engineering UA-cam Channel and follow our other social media handles.
Your Suggestions are Always Welcome!
Best!

Phenomenal explainer. Thank you from Australia. Keep it up.

[@Coreengineers]

Welcome and Love you from India🇮🇳❤️

[@benhalimamohamed9446]

Thanks for information

[@fkp1692]

FO and FC are normally single-acting actuators. Double-acting Actuators are used on "Fail last position valves" but double-acting are NOT necessary "fail last position". Double-acting definitely are NOT fail-safe.

[@saikrishnasai2686]

Sir please make a video on PT,FT,LT etc

[@Coreengineers]

sure! there are already so many videos I have made about the instrumentation topics in the instrumentation playlist

[@saikrishnasai2686]

@@Coreengineers ok sir thankyou

[@fkp1692]

If "Fail Last" the same as "Fail Locked"? Are they the exact same thing, just different ways to say it?

[@devgupta9648]

yes
